I Application December 27, 1948', se ialive smim ,1 This invention relates toimprovements in' a combined lock and door handle.

The mainobjeots of this invention are:

First, to provide a combined handle and door lock in which a latch may be actuated by a push button finger piece, means being provided for preventing the actuation of the finger piece and thereby preventing the releasing of the latch and in effect providing a lock therefor.

Second, to provide a door handle having a pull grip in which a latch may be released by a push button action with the hand that-grasps the handle. v

Third, to provide a door handlefembodying' these'features or advantages which is attractive in appearance and easily manipulated.

Objects relating to details and economies ,of the invention will appear from the description to follow. The invention is pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in

which? Fig. 1 is a fragmentaryview partially in section on a line corresponding to line l-l of. Figs. 2 and 4 ofa combined handle and lock structure embodying my invention.

Fig. 2 is a fragmentary view partially in sec- 3 Claims. (01104-181) tion on a line corresponding to line.2-2 of Figs.

1 and 4, the key being shown in position in the lock and with the parts in locked position.

Fig. 3 is a fragmentary sectional view corresponding tothat of Fig. 2 with the parts inlatch releasing position.

Fig. 4 is an enlarged fragmentary view in section on line 4-4 of Fig. 1 showing structural details.-

Fig. 5 is a fragmentary view in section on a line corresponding to line 5--5 of Fig. 3.

Fig. 6 is a perspective view of the cylinder or casing of the lock barrel or body member.

Inthe accompanying drawing i represents the front panel of a door such as the door of an automobile. A reinforcing plate 2 is secured to the inner side thereof this plate having a flange 3 extending inwardly therefrom and on which the latch mechanism, designated generally by the numeral 4, is mounted. The catch or detent portion of the latch is indicated at 5. The latch is, provided with a trip member 6 having a foot portion 1. The latch forms no part of my present invention and is, therefore, not described in detail herein.

The handle 8 is provided with a grip portion 9, its inner end being provided with a stud I0 arranged through the door panel and the plate 2 and secured thereto as by, the nut II. The handle isv provided with a chamber l2 and has a bracket is fixedly secured to the sides M of the handleas indicated at I5. This bracket projects through the opening l6 in'th'e door and has a threaded opening l'l, receiving the attaching screw Ill "which is arranged through the flange 3 of the reinforcing plataf This' scr'ew is inclined and when tightened draws the handle down against'the outerxside'of the door.

,The'actuating plunger l8 is mounted toreciprocate through the opening I9 in the inner'end ofthe bracket to coactwith the foot piece of the latch releaseimember 6-. t V

The bracket isprovided with inwardly projecting flanges 20 on which the sleeve-like lock casing member 2| is mounted. This casing member has laterally projecting arms 22 disposed on the under side of the ,fianges20 and secured thereto desirably by spot welding as indicated at 23. The casing member has a longitudinal slot 24 adapted to receive the tumblers or bolts of thelock. The casing member also has a longitudinal recess 24! extending the entire length thereof as shown in Figs.v 1 and 6, which is also adapted to receive the bolts or tumblers 25 of the look, as hereinafter described. These are conventionally illustrated at 25 and they are adapted to be projected as indicated in- Fig. 2 into the slot 24.- H Thebody or barrel member 26 of the lock is mounted in the casing member for rotative and axial or longitudinal movement therein and is provided with a head 21 projecting through the opening 2B provided therefor in the handle and constituting a push button or finger piece.

"This barrel or body member 25 is provided with groove-like recesses '29 adapted to be brought into alignment with the stop lugs 30 disposed in opposed relation on 'the bracket flanges 20.

When these recesse 29 are aligned with the stop lugs the barrel may be reciprocated to latch. releasing position as shown in Fig. 3.

The parts arefshown in locked position in Fig. 2. The key 3| is, illustrated. When in locked position they cannotbe manipulated to release the latch until the tumblers or boltelements are retracted. In Fig. 3 the parts .are shown in latch releasing position in which position the lock body or barrel member has been rotated to align the recesses 29 thereof with the stop lugs 30 and to align the tumblers or bolt elements 25 with the recess 24! thereby permitting removal of the key in the unlocked position of the lock or barrel member. The plunger is secured to the inner end of the lock body or barrel member 26. The parts are biased to retracted position by means of the coil spring 32 seated at its inner end on the bracket with its outer end .engaging the thrust shoulder 33. The stop 34 on the plunger limits the return or retracting movement of the plunger and the lock body member. With the parts in the position shown in Figs..1 and 3 the latch release member 6 may be actuated to releasing position by pressing upon the head 21, which as stated constitutes a push button.

To look the parts the head 26 is rotated to re ister the bolts or tumblers 2!" with the keeper slot 24 and bolts or tumblers projected into thev slot. In this position the shoulder; 35 of the body member engages the stop lugs 3B so that the lock body member cannot be rotated or reciprocated axially or longitudinally until the lock' is unlocked to permit the rotation of the body member.

I have illustrated and described my inventionin a highly Practical; commercial embodiment thereof. The structure illustrated'being primarily designed as afhandle and lock for automobile. doors althoughitfwould be'well adapted. for refrigerator doors where itisdesired to lock them. Ihave not attempted toillustrateor describe'other embodimerits or adaptations ,or 'mylinvention which I contemplate as it isbelie ed that this. disclosure will enable those skiIIedQinthe' varti'to embody or adapt myinvntion, as rn'aylbe desired.
